The objective of this paper is to present modeling and simulation of the effect of head restraint position on head/neck dynamics in rear-end motor vehicle collisions. Although individual injury tolerance levels vary, it is believed that properly positioned head restraints can be beneficial in reducing injury. The paper discusses the effects of restraint positioning by simulating a series of rear-end collisions using a finite-segment (lumped-mass) model of the human frame. It is found that proximity of the restraint to the head is the principal factor in preventing harmful whiplash motion. The findings suggest that "smart" head restraints could therefore significantly reduce whiplash induced injuries.
